Integers ending in a 0 (or os) are ambiguous cases. 240 could be rounded to the nearest 10 so that the accuracy is +/-5 or it could be rounded to the nearest unit so that the accuracy is +/- 0.5
The accuracy to which you can take into account the mass of the spring, and the accuracy and consistency of spring tension data inherently limit the accuracy of an inertial balance.
The limit of accuracy refers to the point at which increasing the precision or detail of a measurement or calculation no longer produces significantly more accurate results. This limit is determined by factors such as equipment capabilities, inherent uncertainties in measurements, and the laws of physics governing the system being studied. Exceeding this limit may result in diminishing returns or increased error.
There is a maximum weight limit for parachuting. The maximum weight limit for tandem students is 220 lbs., and the maximum weight limit for AFF students is 240 lbs.
Its simply a matter of statistics. After about ten half-lives, the accumulated error adds up and overwhelms the accuracy of the result.
Limit watches are generally considered to be reliable timepieces, offering decent accuracy for everyday wear. Most quartz models typically maintain accuracy within ±15 seconds per month, which is standard for quartz watches. However, their accuracy can vary based on the specific model and movement used. Overall, while they may not match the precision of higher-end brands, Limit watches provide good value and performance for their price range.

A #6 aluminum conductor will limit the voltage drop to 3% or less when supplying 20 amps for 200 feet on a 240 volt system.
To the present limit of the state of the art in laboratory measurement accuracy, there are 10.
A #10 copper conductor will limit the voltage drop to 3% or less when supplying 21 amps for 150 feet on a 240 volt system.
All measurements are estimations, since it is not possible to measure anything with 100% accuracy, although some things can be measured with a very high degree of accuracy. There is always some limit to the significant digits with which a measurement can be made. You might measure the weight of your sample to the millionth of a gram, or conceivably to an even higher degree of accuracy if the experiment requires it, but you cannot measure it to the last atom. There is a limit to even the finest scale.
A 3/0 copper conductor will limit the voltage drop to 3% or less when supplying 200 amps for 200 feet on a 240 volt system.
A 1/0 aluminum conductor will limit the voltage drop to 3% or less when supplying 30 amps for 500 feet on a 240 volt system.
